1.制作障碍系统 （1.制作几种类型的障碍物的预制体 （（*.编写障碍物基类，以下几种均继承自基类，含碰撞体，RememberY（生成障碍物时该有多大的Y） （（1.矮障碍，仅碰撞体 （（2.高障碍，仅碰撞体 （（3.可冲破障碍 （（（1.除基本碰撞体外，额外包含一个触发器，比碰撞体先检测到马，同时获取马的x速度，大于阈值则给障碍做破碎，用马的力度决定破碎力，关闭碎块和马的碰撞 （（（*.导入某2D破碎插件 （（4.人马分离障碍 （（（WAIT，需要等待人马分离系统先搭建 （2.编写障碍物生成系统 （（1.每若干时间，生成一个随机一种障碍，若干的范围可控 （（（1.设计协程，从预制体列表中随机出一种，并在计算好的位置实例化，随后等待范围内的若干时间，然后检查马的存活情况，若马仍存活，重新调用本协程 （（2.生成的位置：x在相机右侧若干不变距离，y根据障碍物的不同而不同，需要计算保存。 （3.编写障碍物消亡系统 （（1.每个障碍物和碎片都会在离开镜头后被删除
